Reports of roof flaws have often involved asphalt shingles, but premature deterioration has also affected concrete shingles. Consumers who purchased faulty roof shingles have some recourse through class-action lawsuits, although any money recovered may be for the price of the shingles only and not for the cost of the roof installation. Companies that have faced class-action lawsuits because of defective roof shingles include CertainTeed, GAF, Owens Corning and PABCO.
